Description

Technical Field

[0002] Automobile wheel hub bearings are important rolling bearings for automobiles. They are installed in automobile wheel hubs. Their main function is to bear and provide precise guidance for the rotation of the wheel hub. They bear both axial and radial loads and are a very important component. The wheel hub bearing consists of an outer ring, a roller bearing, an inner ring and a cage. The working principle is similar to that of ordinary bearings. They all use the rolling of steel balls in the inner ring, outer ring or flange raceway to carry and rotate relatively. Automobile wheel hub bearings have gone through the first generation of double-row angular contact ball bearings, the second generation of double-row angular contact ball bearing assemblies with flanges on the outer ring, and have developed to the current third generation of double-row angular contact ball bearing assemblies with flanges on both the inner and outer rings.

[0003] The inner and outer ring flanges of the third-generation wheel hub bearings both have contact ball raceways. The raceway of the inner ring flange can be ground by a traditional grinding wheel grinder, while the raceway of the outer ring is located on the inner wall of the flange. A small grinding wheel needs to be inserted into the flange for grinding. Since the shapes of the inner and outer ring raceways of various types of bearing flanges are slightly different, the angle of the grinding wheel needs to be adjusted when processing the outer ring raceway. This results in a rotating joint with low structural strength between the grinding wheel mechanism and the grinder body, which is prone to structural problems such as loosening and shaking during the grinding process, affecting the grinding accuracy.

[0027] In summary: when the automated wheel hub bearing flange raceway grinder is in use, the outer ring flange 5 is placed on the placement table 4 and aligned with the lifting plate 3, and then the outer ring flange 5 is fixed, and then the electric push rod 10 is controlled to be extended and retracted according to the specifications and shape of the raceway groove 501 to be processed, and then the small grinder 11 is driven to rotate at the bottom end of the suspension frame 9 by the adjustment telescopic rod 12, and the transposition linear module 8 is controlled to drive the suspension frame 9 to move horizontally, so as to adjust the angle of the grinding head of the small grinder 11 to adapt to the position of the preset raceway groove 501, and then the hydraulic press 2 drives the lifting plate 3 to drive the small grinder 11 to descend and gradually extend into the interior of the outer ring flange 5, and the small grinder 11 drives the cutter head to rotate at high speed on the inner wall of the outer ring flange 5 for grinding, and at the same time The steering motor 7 drives the steering wheel 6 to rotate along the axis of the outer ring flange 5, so that the cutter head grinds a circle of rolling groove 501 on the inner wall of the outer ring flange 5, realizing automatic processing of the rolling groove 501, and before processing, the transposition linear module 8 drives the small grinder 11 to move to the reinforced assembly component on one side, so that the reinforced assembly component assembles two reinforcing buckle plates 13 on the bottom end of the suspension frame 9 and the small grinder 11, protects the connection between the small grinder 11 and the suspension frame 9, fixes the angle and position of the small grinder 11, strengthens the structural strength of the rotating joint of the small grinder 11, and prevents structural problems such as loosening and shaking during the grinding process. By setting the reinforced assembly component, before grinding, the staff will be connected with the current small grinder 1 1 Two reinforcing gussets 13 adapted to the angle are respectively hung on the hanging claws 34 on both sides, and the transposition linear module 8 drives the small grinder 11 to move to the reinforced assembly component on one side. At the same time, the X-axis linear module 14 drives the support frame 15 to carry the top Y-axis bidirectional linear module 16 and the right-angle frame 17 to move synchronously to the small grinder 11, so that the small grinder 11 is located between the two reinforcing gussets 13. Then the Y-axis bidirectional linear module 16 drives the two right-angle frames 17 to approach each other, so that the two reinforcing gussets 13 are buckled on the small grinder 11. At this time, the first fastening cylinder 18 and the second fastening cylinder 19 are connected to each other, and the fastening electric push rod 22 drives the small screw gun 23 to move, so that the front end of the small screw gun 23 is connected to the fastening bolt 20, and the small screw gun 23 drives The fastening bolt 20 rotates, and the fastening electric push rod 22 drives the small screw gun 23 to move synchronously, so that the front end of the fastening bolt 20 is screwed on the fastening screw barrel 21, and the two reinforcing buckle plates 13 are locked on the suspension frame 9 and the small grinder 11. Then, each power component is reset to complete the automatic assembly of the reinforcing buckle plate 13, so that the bottom end of the suspension frame 9 and the small grinder 11 are stored in the limit groove 1301, so that the reinforcing buckle plate 13 plays a protective and reinforcing role on the rotating joint of the suspension frame 9 and the small grinder 11, avoiding the loosening of the joint due to the vibration of grinding. At the same time, the angle of the small grinder 11 is fixed and strengthened to prevent the small grinder 11 from deflecting during the grinding process and affecting the processing quality of the raceway groove 501. By setting two reinforcing assembly components,Before the grinding process, different reinforcing gussets 13 can be hung on the two reinforcing assembly components. Since the outer ring flange 5 is generally provided with two rolling grooves 501 inside, and the two rolling grooves 501 have different shapes and specifications, the small grinder 11 needs to be adjusted to different angles and positions. When the first rolling groove 501 is processed, the outer ring flange 5 is turned over, and the first reinforcing assembly component removes the first set of reinforcing gussets 13. The small grinder 11 is moved to the other side after adjusting the angle, and the second reinforcing assembly component assembles the second set of reinforcing gussets 13 on the small grinder 11, so that the two reinforcing assembly components can provide different reinforcing gussets 13 to strengthen the small grinder 11 for the processing of different rolling grooves 501 respectively. By setting the flower pattern The shaped sleeve 24 and the guide screw ring 26 make it possible for the fastening bolt 20 and the fastening screw barrel 21 to be rotated out and removed from the guide screw ring 26 after a set of fastening bolts 20 and fastening screw barrel 21 have been used for many times, and the nut 25 is screwed off to take out the fastening screw barrel 21, and the fastening bolt 20 and the fastening screw barrel 21 are replaced to prevent the fastening of the reinforcing buckle plate 13 from being affected by wear of the two. At the same time, when installing the fastening bolt 20, one end of the fastening bolt 20 can be screwed into the guide screw ring 26 until it is flush with the end surface of the first fastening barrel 18, so that the head positions of the new and old fastening bolts 20 are kept consistent, which facilitates the docking of the small screw gun 23 with the fastening bolt 20. By setting the external reinforcement slots 1302 and the fastening screw barrel 21, the staggered external reinforcement slots 1302 can make the two reinforcement buckles The plates 13 are different, which makes it easy to assemble on different right-angle frames 17 and connect with the small screw gun 23. At the same time, when the two reinforcing buckle plates 13 are assembled on the small grinder 11, the two groups of external reinforcing plug plates 27 will be respectively inserted into the opposite external reinforcing slots 1302 to limit the two reinforcing buckle plates 13, which not only facilitates the screw connection between the fastening bolts 20 and the fastening screw barrel 21, but also improves the connection strength of the two reinforcing buckle plates 13 from the outside. By setting the internal reinforcing plug rod 28 and the internal reinforcing slot 1303, when the two reinforcing buckle plates 13 are merged, the multiple internal reinforcing plug rods 28 on one side will be respectively inserted into the multiple internal reinforcing slots 1303, so as to prevent the two reinforcing buckle plates 13 from being misaligned from the inside and improve the connection strength of the two reinforcing buckle plates 13 from the inside. By setting the disc-shaped tooling 29, before installing the outer ring flange 5, the disc-shaped tooling 29 matched with the outer ring flange 5 can be placed on the placement table 4, and the flower-shaped plug rod 30 at the bottom of the disc-shaped tooling 29 is docked with the flower-shaped slot on the top of the placement table 4 to prevent the disc-shaped tooling 29 from rotating. Then, the flange hole 502 on the outer ring flange 5 is docked with multiple positioning columns 31 to position the outer ring flange 5. When the small grinder 11 processes the raceway groove 501, it will apply a vertical downward component force to the outer ring flange 5, so that the outer ring flange 5 is pressed against the disc-shaped tooling 29. The modularization of the tooling of the outer ring flange 5 can be realized through the disc-shaped tooling 29, so that the corresponding outer ring flange 5 can be replaced for different outer ring flanges 5. By setting the positioning screw ring 32,After the outer ring flange 5 is placed on the top of the disc-type tooling 29, at least one positioning screw ring 32 can be screwed onto the positioning column 31, so that the positioning screw ring 32 is locked on the top of the outer ring flange 5. When the small grinder 11 processes the rolling groove 501, the positioning screw ring 32 can cooperate with the vertical downward force to prevent the disc-type tooling 29 from moving up and down and affecting the processing quality of the rolling groove 501. By setting the chip discharge hole 2901, during the process of the small grinder 11 processing the rolling groove 501, the waste chips generated by grinding will fall on the conical disc 33, slide along the inclined surface of the conical disc 33 to the chip discharge hole 2901, and finally fall into the collection box inside the grinding machine body 1, realizing the automatic discharge and collection of waste chips.
